    Have the same problem in left lower corner with KDF-60WF655. Also, small light blue dots are taking over my screen. Like a constellation, started small amount of dots and continue to increase in number.

    I have the same problem. It started after we replaced the bulb. It seems to be moving around the screen.

If you go to the Sony website they are fixing this problem for free if you purchased your tv within a certain timeframe. It was fixed for us- it is a $900.00 repair. The technician said to vacuum the back of the set every week to help prevent this- you need to contact them quickly as I believe the offer is up in December for the free repair.

Mine has it too. Tech told me its dust on the "LCD" sometimes they work them selves out.
Try vacuuming the back side of the tv, and continue to do so at least once every 3 months.

Sony WEGA 42" LCD TV


Uh Oh! blue screen of death. Your light engine has warped a little from overheating and is distorting the picture.

My suggestion to you is to get on the phone with Sony and start complaining, then keep complaining until they agree to pay for it. Even if it is out of warranty.
You may have to get the problem diagnosed by a pro before they agree to pay for it though.
Hope ya fix it!

Bright blue spots on lower right corner of Sony Grand WEGA KF50WE610 50 in. Rear projection tv


The spots are from dust in the optical assy. It would need to be replaced because the only way to fix the part would be to disasemble it in a dust free room.
